U-shaped dumbbell and ergonomic kettlebell

ABSTRACT

A dumbbell has a left weight, a right weight, and an arched handle connected to the tops of the weights. In preferred embodiments, the bottoms of the weights are flat, the weights are at least as wide as they are tall, and the weights are parallel to each other. This configuration combines the advantages of a dumbbell and a kettlebell. The arched handle enables kettlebell-like arm raises, while the dumbbell configuration keeps the weights from pressing into the wrist. The arched handle also enables stable placement of the dumbbell over legs, knees, elbows, and ankles.

1. FIELD OF THE INVENTION

This invention is in the field of exercise devices, specifically free weights.

2. BACKGROUND OF THE INVENTION

The invention is an ergonomic and versatile improvement over traditional kettlebells and handheld dumbbells. Traditional kettlebells, handheld dumbbells, and ankle weights offer limited versatility when it comes to working out certain regions of the body, primarily because they are not ergonomically designed to contour to the body's natural curved shape, and as a result cannot be comfortably hooked onto a specific body region such as the back of the leg, on top of the ankles, or side of the leg to offer resistance to a specific part of the body.

3. DESCRIPTION OF RELATED TECHNOLOGY

Conventional kettlebells have a solid piece of steel, usually in a circular shape, see FIG. 10 (Prior Art—Traditional Kettlebell—front view) and FIG. 11 (Prior Art—Traditional Kettlebell—side view gripped with one hand gripping). Traditional kettlebells vary in dimensions, and the additional weight gets added to Part 8 (Solid Weighed Part of Handle part of the Prior Art—Traditional Kettlebell), with an arched handle, see Part 7 (Arched Handle part of the Prior Art—Traditional Kettlebell) that wraps around the Solid Weighed Part of the Handle. The arched handle (7) gives the user the ability to comfortably grip the weight with either one or two hands, and swing the weight while performing workouts such as kettlebell swings. The arched handle also allows the user to comfortably grip the weight while performing the deadlifts (either with one or both hands).

The problem that occurs when the user is performing arm raises using a Traditional Kettlebell is that the weighted round steel ball (8) ends up putting uncomfortable painful pressure against the wrist and arm of the user. See FIG. 11 . This happens when the user lifts the traditional kettlebell weight above their head in the workout example shown in FIG. 18 . (Turkish Get Up), where the user starts with a bent elbow holding the weight and then extends the arm overhead. In the case where the traditional kettlebell is used, the user would experience uncomfortable pressure against their wrist and arm from the weight Solid Weighed Part (8) being pushed against their arm and wrist, as indicated in FIG. 11 . This can be especially uncomfortable and painful as the weight of the traditional kettlebell increases. In addition to putting uncomfortable pressure on the user's wrists traditional Kettlebells also have limitations while performing a variety of other workouts such as the following.

(1) Donkey kicks (see FIG. 14 .) and fire hydrants workout: Traditional kettlebells have a closed shape design that prevents the user from being able to hook weight onto various parts of their body such as the back part of their leg while performing the donkey kicks or fire hydrant workouts with additional resistance.

The other option the user has for adding resistance weight while performing the donkey kicks and fire hydrants workouts is using a traditional hand-held dumbbell, see FIG. 30 (Prior Art—Hand-Held Dumbbell with side plates version straight view) and FIG. 31 (Prior Art—Hand-Held Dumbbell, solid piece version, side perspective view).

But the problem with handheld dumbbells is that they are not designed for the legs because of the positioning of the handle (13) which is in the center of the side weight plates (14) and the lack of a curved handle, so as a result of their current design, hand-held dumbbells are extremely challenging to keep in place behind the back of the leg while performing the donkey kicks and fire hydrants, and oftentimes end up falling off the user's leg causing potential injuries to the user. In most cases, the user has to focus their energy on squeezing the handle with their leg at the top of each repetition in an attempt to prevent the hand-held dumbbell from falling off their leg, instead of focusing their energy on squeezing their glute muscle (which offers the best maximum results) as a result the user does not gain the best maximum results of the donkey kicks and fire hydrants workouts because of the challenges associated with trying to keep the hand-held dumbbell from falling off from the back of their leg.

(2) Standing Leg Raises (see example in FIG. 16 .): in this case, the closed shape design of the traditional kettlebell prevents the user from being able to place the weight on top of the ankle and foot, and hand-held dumbbells don't even have a chance of staying in place because of their straight handle design and lack of length in the side weights Parts 14 and 15.

(3) Side Leg Raise workout (see example in FIG. 22 .): the closed shape design of traditional kettlebells and the straight handle of hand-held dumbbells do not allow the user to hook the weight to the side of their leg for added resistance while performing the side leg raises.

(4) Knee Tucks workout (see example in FIG. 24 .): These are impossible to perform while using traditional kettlebells and hand-held dumbbells for the same reasons described above. Kettlebells' closed design and the straight handle of handheld dumbbells prevents the user from hooking them onto any other body part such as on top of the ankles while performing the knee tucks workout.

(5) Supported Push-ups workout (see example in FIG. 27 .): The circular base of the Traditional Kettlebells can cause the weight to roll over while performing the supported pushup using two kettlebell weights, causing potential injuries to the user.

(6) Extended kickback leg workout (see example in FIG. 55 .): As mentioned above, the user cannot possibly hook the traditional kettlebell on to any part of their body including the lower leg, and hand-held dumbbells straight handle design and lack of length in the side weights prevents the user from being able to safely place the weight behind the lower part of their leg while performing the extended kickback leg workout.

Overall the traditional kettlebells put uncomfortable pressure on the wrists when lifted up over head and offer the user a limited amount of workouts because of their closed-shape design that prevents the user from being able to hook the weight onto various parts of their body, such as the back of their leg, their ankles, and side of the leg.

Traditional hand-held dumbbells' straight handle design does not offer the versatility of kettlebell's arched handles to perform workouts such as the kettlebell swings and deadlifts. And traditional hand-held dumbbell's lack of and arched handle and left and right side weight length does not allow for the weight to stay securely and safely behind the user's leg while performing the donkey kick and fire hydrant workouts, nor allow the user to hook the weight onto any other body parts (such as the back of the leg, top of the ankle, or the side of the leg for example) to offer the user additional versatility.

And ankle weights have limited uses, for example the user cannot use the ankle weights to perform workouts such as the deadlifts FIG. 20 ., supported pushups FIG. 26 , thruster FIG. 12 , arm raises and many more that the new invention can. In addition ankle weights take extra time to take on and off which is not ideal during high interval training where the user needs to maintain momentum to keep the heart rate going to gain the full maximin benefits of a HIIT workout.

4. SUMMARY OF THE INVENTION

The invention solves all of the problems stated above of using the prior art of traditional kettlebells, dumbbells, and ankle weights, all while offering the user additional versatility.

The invention is composed of three parts: a left weight, a right weight, and a handle. The left end of the handle is connected to the top part of the left weight, and the right end of the handle is connected to top part of right weight.

There is an opening between the base of the left weight and the base part of the right weight. This creates a space at the base between the bottom parts of the weights with the handle at the top. All together the three parts create an upside-down U shape that allows the user to hook the invention onto various parts of the body.

The handle can be gripped with one hand or both hands and it can be hooked behind the user's leg, the side of the leg or on top of the ankle. The handle of the invention can be straight or arched, the arched version allows the user to grip the Handle with their hands like a kettlebell to allow the user perform workouts.

The handle can be uniform in thickness or have varying thicknesses, so it can be thicker and thinner in various areas. The handle is smooth around the exterior for the user to comfortably grip, in other words, there are no sharp edges on the handle of the invention.

The weights can be in VARIOUS shapes and thicknesses, including a heart version, oval version, round version, rectangle version, and cylinder uniform version.

All parts can also be ALL UNIFORM in shape and thickness.

All parts can be one whole unit or be separated into parts and reconnected with male and female threads that can be twisted into each other at opposite ends.

The entire invention can be made of a hard material such as steel, metal or plastic material to maintain the upside down U shape. All parts can be solid or hollow on the inside. The solid version is made out of a heavy material such as steel. The hollow version has an opening at the top to allow a material such as water or sand to go inside of it and be sealed when attached to each other.

The separate interchangeable weights can be in any shape, length, width, weight, and size, as long as they are connected to the handle ends.

The side weights are not limited to being straight nor indented on both sides, in other words, they can be straight or indented at the base.

6. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Section (1) handle is indicated by the letter C and Part 1 (see FIG. 1 ). The handle is ideally arched, as seen best in FIGS. 1-7 . This handle is not restricted to being uniform in its thickness. In other words, the handle can be thinner in some areas and thicker in others as illustrated in FIG. 32 and FIG. 34 . For the sake of the user's comfort, while gripping the handle, the handle is smooth around the exterior handle Part C.

Section (2) the left weight is indicated by the letter A in all figs drawings and Section (3) the right weight is indicated by the letter B in all figs drawings. These parts are not limited to a particular shape, size, dimensions, circumference, or thickness. In other words parts, A and B can be in a variety of shapes and sizes such as the shape of a triangle as indicated in FIG. 5 or a heart version as shown in FIG. 4 . FIG. 32 shows the parts with various thicknesses, while FIG. 35 shows uniform thickness. FIG. 36 (Cylinder uniform arched handle version), FIG. 42 (Oval version with a rounded and flat base), and FIG. 46 (Rectangle version) are some visual examples of various versions of the invention.

FIGS. 6 and 7 juxtapose two alternatives in which the weights may be tapered (FIG. 6 ) or parallel (FIG. 7 ). FIG. 5 presents an important embodiment in which the bottoms of the weights are flat. The flat configuration prevents the barbell from rolling when it is placed on the floor, which is especially useful during exercises like supported pushups (FIG. 26 ). The weights may assume any aspect ratio. As shown in FIGS. 4 and 5 , they may be at least as wide (from front to back) as they are tall (from top to bottom).

Parts C the handle and parts A left weight and B right weight can be one solid unit or separated as illustrated in FIGS. 39, 41, 43, and 45 .

The solid one-piece version of the invention can be made using one mold, with any hard material such as steel or cast iron. It can be left in its raw form, painted or coated in rubber.

In the version where all parts can come apart as illustrated in FIG. 39 , the Part C handle part of the invention can have a cushioned sleeve that goes over it to give the user a softer and more comfortable grip.

The parts A left weight and B right weight can be attached and detached to and from the handle in multiple ways, one way is with Part 18 Male Threads and Part 19 Female Threads opening for male threads, where the female threads are screwed into the male threads securing the weight in place. See FIG. 39 .

The A left weight and B right weight can be in any shape and length and can also be configurable and interchangeable. For example in FIG. 39 . Parts A and B can be broken up into smaller parts where the user has the option of adding more weights by screwing more weights into each other. These interchangeable Parts A and B can be in any shape, length, width, weight, and size.

Parts C the handle and parts A left weight and B right weight are not restricted to being solid on the inside. In other words, all of the parts of the invention can be hollow and filled with heavy material such as water or sand, illustrated in FIGS. 57 and 58 .

The triangle version is especially user-friendly when getting filled up with heavy material because it ensures that there are no air holes, thus preventing any sloshing if filled with water. The hollow version is especially useful when traveling, allowing the weight to stay light for easy travel. Then when the user is ready to workout on the beach for example they can easily fill up the weight with sand or ocean water, for example, to allow the weight to become heavier with the contents. Then when the user is done with their workout they can easily empty Part 22 (Heavy material such as water or sand) out of the weights, as in FIG. 57 .

Part C Handle part of the invention can be straight or arched. The arched version is more user-friendly because it allows the user to place the invention behind the back of their leg allowing the invention to contour to the user's body more effectively, illustrated in FIGS. 55 and 56 .

In addition, the arched handle version of the invention allows the user to comfortably grip the handle with both hands (either one or both) much like a traditional kettlebell to perform a wide variety of workouts. See FIGS. 21 and 43 . But unlike traditional kettlebells that have a closed-shaped design as indicated in FIG. 10 , which puts uncomfortable pressure on the wrists (see FIG. 11 ), the invention has an open space between part A the left and right side of part B of the invention that creates an opening between them for the user's wrist to clear while lifting see FIG. 13 .

To increase in weight the invention's side weights parts, A and B can be increased in thickness, width, height, or circumference in various ways, as illustrated by the broken dashed line Part 6, Increased thickness of the invention, in FIGS. 33 and 34 .

The two side weights indicated by Parts A and B of the invention vary in size and thickness depending on the amount of weight the invention needs to weigh. There is no specific weight or dimension that the invention is limited to, it can weigh as little as half a pound and as much as one hundred pounds or more. In FIGS. 6 and 7 , you can see the broken line that indicates the increased thickness of each plate, indicated by Part 6, Increased Rim thickness part of the flat shape of the invention. This line is an example of how the weight would be distributed as it increases in weight while maintaining the same design and functionality proportions of the invention. The weight could also be distributed into the handle, but not past the thickness of what would be comfortable to grip for the user, to allow a comfortable grip by the hands as well.

The reason for the indented base version of the invention is for the two side plates to wrap around the body more snugly. See FIG. 6 . This is more user-friendly when performing the donkey kick and fire-hydrant workouts see FIG. 14 and FIG. 15 . This slight indentation allows the plates of the invention to fit more snugly around the back of the user's leg. It is also important to note there is no limitation on the space between parts A and B weights, there can be a more narrow version for people with slimmer legs and a more wide version for users with thicker legs. The important part is that the handle between the two plates remains arched to comfortably contour to the user's body and stay more securely in place while performing the workouts. Although a straight handle version is also optional, the arched U shape would be more comfortable for the user because it contours to the body's natural curvature shape.

Another version of the invention that offers great support while performing the elevated push-up workout see FIG. 26 and FIG. 27 is the triangle version of the plates, see FIG. 3 and FIG. 5 , because the triangle shape has a flat wide base that will not roll off the ground, making it safer than traditional kettlebells that have a round base that can roll off and cause the user potential injuries.

The handle (marked with the letter C) is connected to the side weights indicated by the letters A and B, these side weights grip and contour to the user's various body parts while performing a wide variety of workouts to offer the user weighted resistance to strengthen specific muscle regions. All three parts A, B, and C make one whole invention that consists of an open area between parts A and B, this open area allows for the user to use the invention in a variety of ways that are indicated in FIG. 13 through FIG. 29 and FIG. 47 through FIG. 55 .

The two sides parts A and B are connected to the handle at the top, creating an upside-down U shape with a space in between them. This open space and the upside-down U shape naturally contours to the user's curved body parts and as a result allows the user to hook the weight onto various parts of their body such as the back or their leg while performing donkey kicks and extended leg raises see FIG. 55 and FIG. 56 . The two side parts A and B grip the users legs and stay stabilized to securely, safely and comfortably stay in place during each workout. And as a result, making the new invention safer than traditional kettlebells and hand-held dumbbells while performing the donkey kicks and fire hydrants exercises, as well as FIG. 55 . All while offering the additional versatility of performing many other workouts such as indicated in FIG. 13 . through FIG. 29 .

Here is a detailed breakdown explanation of why the invention is more safe, comfortable, and versatile for the user than all of the prior art kettlebells, dumbbells, and ankle weights combined based on the specific exercise performed:

(1) Donkey kicks and fire hydrants: The ergonomic shape of the invention see FIGS. 1, 33, and 36 , for example, allows the user to safely and comfortably place the invention behind the back of their leg while performing the donkey kick and fire hydrant workouts see FIGS. 14, 15, and 37 . The upside-down U-Shaped arched handle Part C of the invention and weighted sides indicated by parts A and B naturally contour to the leg's natural arched shape allowing the invention to comfortably stay in place while lifting the leg.

Traditionally the user would use handheld dumbbells that do not have an offset weighted handle, because of this hand-held dumbbells are hard to grip with the back of the leg. They are uncomfortable to use and frequently end up falling off the leg causing potential injuries to the user. Because hand-held dumbbells are hard to grip with the back of the leg, the user focuses on squeezing the hand-held dumbbell instead of squeezing their glute muscles, which is ideal for maximum results during the donkey kick and fire hydrant workouts. The new invention solves this problem by safely and comfortably staying in place, giving the user the ability to focus on squeezing their glute muscles at the top of every rep for maximum gain results per repetition.

There is no other free weight that has the ability to contour to the leg in this way to offer weighted resistance in the ideal place for the best optional results while allowing the user to quickly take it off and on themselves. As mentioned above hand-held dumbbells do not have the arched shape design to contour to the natural curvature of the back of the leg, and the side weights are not long enough to grip the leg securely. And as a result, hand-held dumbbells are hard to keep in place behind the back of the leg and can end up falling off the leg causing the user potential injuries. And unlike ankle weights that take extra time to take on and off, the invention is super fast and easy to take on and off during interval training, allowing the user to maintain momentum for the best optional results when switching workouts.

(2) Standing Leg Raises: The problem with using ankle weights is that they take extra time to take on and off during interval training and offer limitations in the amount of weight they can go up in because they have to be attached to the user's body, as well as limitations on not being able to perform other workouts such as the deadlifts FIG. 20 ., supported push ups FIG. 26 , thruster FIG. 12 , arm raises and many more that they new invention can.

The invention allows the user to easily hook it on top of their ankle in seconds, see FIG. 16 . Starting (1) and ending (2) of Standing Leg Raises workout using the invention, FIG. 17 . Close-up view of Standing Leg Raises workout using the invention and FIG. 48 . Close-up view of Cylinder uniform thickness version—placed on top of user's ankle/foot while performing standing leg raises. The invention upside down U arched shape naturally contours to the top of the user's ankle while lifting their leg up, allowing the weight to stay in place while offering the needed resistance for targeting the front part of their thighs and core muscles, safely and effectively.

In addition, the new invention is easy to take on and off, making the transition from one workout to another super fast and effortless. This is especially important during high interval training where the user needs to quickly transition from one workout to the next without any rest. For example, the user would start in the standing position with the invention on the floor, then quickly and easily hook the invention to the top of their foot while performing the standing leg raises. When finished with their reps the user can easily transition into a single-leg deadlift see FIG. 28 . Starting (1) and ending (2) of Single Leg Deadlifts workout using the invention. FIG. 27 . Close-up view of Supported Push-Up workout using the invention. This fast and effortless transition is especially beneficial for HIIT (high interval training workouts), where the user needs to keep their heart rate up to gain the maximum benefits in the shortest amount of time. And the invention is the only one that allows the user to perform these exercises without having to take extra time to switch equipment, saving them time to maintain momentum for the best optional results.

(3) Side Leg Raise workout: Using ankle weights or resistance bands, as mentioned above ankle weights and resistance bands take extra time to take on and off which are not ideal during high interval training and ankle weights can be limited in weight because of being attached to the body. In addition resistance bands do not offer the full range of motion needed to isolate and target key muscles, so they are not as effective. The invention solves this problem because it can easily be placed on the side of the leg while performing the side leg raises, see FIG. 22 . Starting (1) and ending (2) of Side Leg Raise workout using the invention and FIG. 23 . Close-up view of Side Leg Raise workout using the invention. Because the side of the leg is naturally curved it allows the invention to safely and comfortably stay in place while lifting the leg up, allowing a full range of motion for the maximum benefits.

(4) Knee Tucks: the upside-down arched U-arched shape of the invention allows the user to easily place the weight on top of their ankles while performing the knee tucks workout, see FIG. 24 . Starting (1) and ending (2) of Knee Tucks workout using the invention, FIG. 25 . Close-up view of Knee Tucks workout using the invention and FIG. 50 . Close-up view of Cylinder uniform thickness version—hooked on top of both ankles of the user while performing knee tucks. This allows the user to achieve resistance to target and tone their lower abdominal muscles, quickly and easily and with a full range of motion.

(5) Supported Push-ups: As mentioned above the triangle-wide base version of the invention see FIG. 3 . Triangle Version—top perspective view, offers a sturdy base while performing the supported pushups workout, see FIG. 26 . Starting (1) and ending (2) of Supported Push-Up workout using the invention and FIG. 27 . Close-up view of Supported Push-Up workout using the invention. This sturdy base prevents the weight from rolling over, solving the problem of the round-based kettlebell of the prior art.

(6) Arm Raises: the new invention has an open space that clears the area for the weight not to be in the way of the wrist see FIG. 13 . Close-up view of the hand gripping the invention at the end of the Thruster workout, thus making the workout much more comfortable and safer for the user compared to a traditional kettlebell weight that would put pressure on the user's wrists, see FIG. 11 . Prior Art—Traditional Kettlebell—side view gripped with one hand gripping.

The invention allows the user to perform all of the workouts that a traditional kettlebell does like the kettlebell swings and the deadlifts see FIG. 20 . Starting (1) and ending of the (2) Deadlift workout using the invention. But because of the invention's ergonomic open upside down U-shaped design which creates space for the user's wrist and arm see FIG. 19 . Close-up view of Turkish Get-Up workout using the invention while performing workouts such as the Turkish Get-Up see FIG. 18 . Starting (1) and ending (2) of Turkish Get-Up workout the invention, and the Thruster workout see FIG. 12 . Starting (1) and ending (2) of Thruster workout using the invention. In FIG. 13 . Close-up view of the hand gripping the invention at the end of the Thruster workout you can clearly see how the open U-shaped design of the invention creates space for the user's wrist and arm, and as a result makes performing these workouts more comfortable for the user while decreasing potential injuries to the wrist when lifting the weight, especially in the cases where the weight amount is increased.

Overall the new invention is like a kettlebell, hand dumbbell, and ankle weights in one product, with the additional versatility of allowing the user to hook the weight safely and comfortably onto various body parts for extra resistance. This makes the new invention the most versatile free weight.
